Multiple-Baseline Design Across Participants

Multiple-Baseline Design Across Behaviors

Multiple-Baseline Design Across Settings

What is the primary defining characteristic of a multiple-baseline design in single-subject research?

Observe the provided graph of a multiple-baseline design. Arrange the following implementation steps in the correct order to reflect how this design demonstrates that a treatment is responsible for behavioral changes.

A researcher is designing a single-subject study to evaluate a new intervention while avoiding the ethical issues associated with withdrawing a treatment. Match each research scenario to the specific type of multiple-baseline design it represents.

In a multiple-baseline design, if a researcher observes that behavior across all participants improves at the exact same moment the treatment is introduced to only the first participant, this outcome provides strong evidence that the treatment is the cause of the change.

Match each variation of the multiple-baseline design to the focus of its baseline measurements.

In a multiple-baseline design, what is the interpretive purpose of staggering the introduction of the treatment across participants, as shown in the provided graph?

A colleague critiques a study on social skills training by suggesting that participants' improvement was simply due to maturation—becoming more comfortable with the observer over time. To rebut this, the researcher points out that the third participant's behavior remained at baseline levels for several weeks until the treatment was finally introduced, even though the other participants had already received it. The ability to rule out threats to internal validity like maturation by staggering the timing of treatment introduction is the core evaluative strength of the _____.

A school psychologist wants to evaluate a self-quieting intervention for a student. They establish baseline measurements of the student's disruptive behavior in three different settings: the classroom, the playground, and the cafeteria. They then introduce the intervention in all three settings simultaneously. True or False: This procedure represents a multiple-baseline design.

A researcher is studying the effects of a token economy on a child's social skills. Because they are concerned that withdrawing the token economy might cause the child's improved behavior to deteriorate, they analyze the limitations of a reversal design and decide to use a multiple-baseline design instead. By selecting the multiple-baseline design, the researcher demonstrates the effect of the treatment without requiring its _____.

A researcher plans to evaluate a reading intervention across three participants using a multiple-baseline design. Order the following steps to describe the correct sequence of implementing the design to evaluate the treatment's effectiveness without removing it.

Describe the multiple-baseline design in single-subject research. In your concise analytical response, explain why this design was developed and outline the three primary ways baselines can be established according to this method.

Based on the provided scenario, decide how the psychologist should implement the intervention to demonstrate its effect without requiring its removal. Justify your decision using the principles of the multiple-baseline design.

A researcher wants to test a new classroom management strategy to reduce disruptive behavior, increase on-task behavior, and improve peer sharing in a specific student. If the researcher wants to avoid withdrawing the strategy once it is implemented, how should they apply a multiple-baseline design to evaluate this single student? Provide a brief one- to three-sentence answer.
